Abstract: An extension spray gun comprising a plurality of hollow pole sections telescopically secured together to form an extendable pole having a spray nozzle secured to one end of the pole and a valve secured to the other end of the pole to control flow of paint through a flexible hose extending between the valve and the nozzle. Paint is delivered from the hose to a chamber formed in the nozzle and flows through a passage in the nozzle to a spray tip. A valve element in the chamber is spring urged to close the passage when pressure of paint in the chamber is less than a predetermined pressure.

Abstract: Disclosed is a shield for sprinklers, which can be quickly attached and detached from a sprinkler standpipe. The shield has a semi-circular deflector mounted at the top of a support rod. A hook is formed in the bottom of the support rod to engage the standpipe. The hook is disposed in a plane substantially horizontal to the support rod, has a slightly helical configuration, and opens in laterally with respect to said rod. Midway of said rod a brace projects from said rod substantially normal thereto and has a standpipe engaging fork in its outer end. The hook readily engages the standpipe when the support rod is parallel to the standpipe and clamps to it when the upper end of the support rod is drawn away from the standpipe to engage the brace with the standpipe.

Abstract: A pipe interior surface coating device having a spray apparatus for distributing a coating material around an axis of rotation. A carriage supports the spray apparatus and is adapted to be moved longitudinally inside a pipe. A bracket may be used to position the spray apparatus at a chosen distance away from one end of the carriage and the carriage may include apparatus to position the axis of rotation of the spray means concentrically within the pipe.
